5-8x / (2+x)(1-3x) , wasn't it?

Your calculator knows the answers?! Wow which genie gave you that


Amazon, before you get cocky. To be specific- this exact model - http://www.amazon.co.uk/Casio-FX-991ESPLUS-SA-UH-FX-991ESPLUS-Scientific-Calculator/dp/B0034BAQS8/ref=sr_1_6?ie=UTF8&qid=1370870952&sr=8-6&keywords=calculator

Which can integrate hence you can check your answer.

I put the original equation in mine, and came out with 11/3ln2 too, so i guess we got our calculators off the same genie.

That was death.

the paper was really hard but i think that a lot of people seem to have got the right answer to a lot of the questions.
I reckon between 60 and 63 for the A*

good luck

and to make you guys feel better... this was harder than FP2.


You dont need to make me feel better dick.

My calculator 'knows the answers' too. Isn't that their sole purpose?

I can't believe not everyone has the 991-ES plus, it's super handy for being able to check answers like that! The summations funtion means you can check cumulative probability distribution answers for stats too - life saver for silly mistakes!

Mate you're full of **** xD


Im being honest. Only a small percentage of the sample taking C4 are on TSR.
Just because the majority here thought it was hard, does NOT mean the rest did.

I am just saying that you should be prepared for when im right, and the boundary for an A is 64
